???? ALPHV/BlackCat Ransomware Gang Targets Americas and Europe ???? 

eSentire’s cybersecurity team warns of Russian-speaking affiliates of the ALPHV/BlackCat ransomware gang targeting corporations and public entities across the Americas and Europe. Recent attempts to breach a law firm, a manufacturer, and a warehouse provider were thwarted by the firm’s Threat Response Unit (TRU). ⚠️???? 

???? How they do it ???? 

ALPHV/BlackCat actors gain initial access through valid credentials, exploitation of remote management services, and browser-based attacks. A notable shift this year includes an affiliate using malvertising, enticing users with Google ads promoting popular software. Unknowingly, users download Nitrogen malware, providing hackers a foothold for further attacks. ????????️ 

???? BlackCat’s paw prints ???? 

Known for ruthless tactics, ALPHV/BlackCat has targeted prominent entities like MGM Resorts and McClaren Health Care, causing operational chaos and compromising sensitive data. The group, connected to former BlackMatter ransomware, has affiliations with the notorious FIN7 cybercrime group. ????️‍♂️???? 

☣️ Malvertising & Nitrogen Malware ???? 

The use of malvertising to distribute Nitrogen malware highlights a growing attack surface. Popular software ads, such as Advanced IP Scanner and Cisco AnyConnect, lure professionals to attacker-controlled sites. Nitrogen’s unique use of obfuscated Python libraries adds complexity for security analysts. ???????? 

????️ Top Tips:

  • Include browser-based attacks in user awareness training. 

  • Implement attack surface reduction rules for script files. 

  • Employ comprehensive endpoint monitoring and logging. 

  • Engage with a Managed Detection and Response (MDR) provider for proactive security.  

Stay safe! ????????
